It seems to me that this isn't useful. The whole reason to have and use
BASH_SOURCE_PATH is not to use PATH; a fallback to PATH if something
isn't found in BASH_SOURCE_PATH doesn't allow that. And if you're using
BASH_SOURCE_PATH, you have to set it, and if you want `.' in there,
add it. If you don't set BASH_SOURCE_PATH (from the user's perspective;
I'm not sure what I think about a loaded `library' changing the global
user settings by setting it), you get the historical behavior.
